To all whom may concern:

lie it known that 1, JOHN A- Nansen, a citizen of the United States,residing at Ne braska City, in the county of (ltoe and State ofNebraska, have invented a new and useful lioailing-Machine, of which thefollowing is a. specification.

The present invention appertains to loading machines, and aims toprovide a novel and improved appliance of that, character which isoperable for loading wagons or other receptacles in. a thoroughlypractical and el'licacious manner.

it is the object of the invention to provide a loading machine embodyingmeans onto which the dirt or other matter to be loaded can be shorelcdor dumped, and adapted to be raised so that the wagon. or otherreceptacle can be moved under said means in which event said means isoperable for dumping the dirt or matter into the Wagon or receptacle,the machine being readily restored for a new operation.

Another object of the invention is the provision of a loading machinehaving means which assumes a relatively iiat or prostrate position whenlowered, to receive the dirt or material, said means when raised beingoperable to provide a hopper for convcniently dumping the material intothe Wagon or receptacle.

It is also the object of the invention to provide a loading machine ofthe nature in dicated possessing novel features to enhance the utilityand elliciency thereof.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts, and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made Within thescope of \th at is claimed, Without departing from the spirit of theinvention.

'1. he invention is illustrated in the accompanying drawings, wherein 1-Figure 1 a plan view of the machine.

Fig. 2 is a side elevation thereof, partly in section on the line 2-:2of Fig. 1.

Fig. 3 is a cross section taken on the line 3--3 of Fig. 1, illustratingthe dirt holding means in raised position.

Fig. l is a fragmental end View illustrating the dirt holding meansraised and operated to provide the hopper.

Fig. 5 is a horizontal section taken on the line of Fig.

The machine embodies a suitable frame preferably constructed of angleiron or other structural material, and including the parallellongitudinal base members or beams 1, the corner standards 2 secured tothe ends of the beams, and the rectangular top memher 2; carried by thestandards. Channelshaped guides are secured to the beams 1 and member 3at the sides of the frame adjacent to the ends thereof, and the ends ofthe frame are preferably braced by crossed braces 5. The frame is ofarch form, in order that wagons or other receptacles can be movedlongitudinally thereunder, in one end and out the other. When themachine is to be moved from one place to another, this can be readilyaccomplished by securing the beams 1 on suitable trucks 6, but the useof these trucks is optional.

The dirt or material holding means is movable vertically within theframe, and embodies an open rectangular frame member or carrier 6constructed of gas piping or other suitable material. 'lransiersesupporting bars 7 re disposed umlerneath the carrier 6 and their endsare slidable in the re spectlve guides l. Upstanding rods 8 are securedto the bars T and are slidable through the longitudinal portions of thecarrier 6. Cables or flexible elements 9 are attached to the bars 7adjacent to their ends and extend upwardly Within the guides 4 and arepassed oi'cr pulleys or guides 10 mounted for rotation. within theguides adjacent to their upper ends. From the pulleys 10, the cables 9extend to and are secured to drums 11 mounted upon a longitudinal shaft12 journaled in end bearings 12 carried by the top member 3, wherebywhen the shaft 12 is rotated in one direction, all of the ables 9 areWound upon the drums for raising the bars '7, and when the shaft isrotated in the other direction, all of the cables 9 will be unwound topermit the bars 7 and carrier 6 to gravitate. As a means for rotat ngthe shaft 12 to Wind up the cables 9, a drum 13 larger than the drums 11is secured upon the shaft 12 and a cable or flexible element 11 isattached to and Wound upon the drum 1%. This cable 1i extends over anddownwardly from a pulley 15 mounted upon the member 3 at one side, andsaid cable then extends under a pulley 16 carried by the frame adjacentto the base thereof. The cable ll can have draftanimals hitched theretoto thereby provide a haul line which can be pulled tor unwinding thecable from the drurn'li to thereby rotate the shaft 12 for winding thecables 9 upon the drums 11, or the cable ll can be pulled by a winch,Windlass, or other suitable mechanism, whereby to raise the dirt ormaterial. holding means when loaded.

The dirt holding ineans also embodies side plates 17 projectinginwardly. and having bearings 18 secured thereto adjacent to theirremote edges, and said bearings rotatably embrace the longitudinalportions of the carrier 6. The remote edges of the plates 17 haveupturned flanges 19, and are also provided with notches 19 foraccommodating the rods 8. The adjacent edges of the plates 17' have downturned flanges 1'20 terini' hating short of the ends of the plates 17.End plates 21 are provided between their ends with lower bearings 22rotatably einbracing the end portions of the carrier 6, whereby theplates 21 as well as the plates 17 are swingable upwardly anddownwardly. The end portions of the plates 17 have resting thereon theinner tapered wings of the plates 21, and the edges of the plates 21 areout obliquely, the adjacent edges of the plates 1? being provided.adjacent to the ends thereof with upwardly curved lips 23 to rideslidably upon the bars 7 The inner and outer wings or" the plates 21 arepreferably at a large obtuse angle relatively to one another, wherebywhen the plates are in lowered position, the outer wings of the plates21 provide runways for the devices for dumping the material onto theplates. Cleats 21 are secured on. the plates 21. to

V aid in dumping said devices. When the bars 7 and carrier 6 havegravitated, the inner wings of the plates 21 in resting upon the plates1.7 are brought to a substantially horizontal position, and the plates21 in resting upon the inner wings oi? the plates 17 are also brought toa substantially horizontal position. The dirt holding means moves into arelatively flat position when it is prostrate in its lowered position,for recei 7 and holding the dirt or other material. lVhen the carrier 6is raised with he bars 7, said bars support the plates 17 which in turnsupport the plates 21, thereby preventing the plates troin. swingingdownwardly with the carrier 6.

Means are provided for supporth'ig the carrier 6 when it is raised, inorder that when the bars 7 are then lowered, this will enable the platesto swing downwardly to provide a hopper. Thus, upwardly projectinglatches 24 are provided at the outer sides oi. the guides 4-, and areseated loosely in notched members 25 secured to the outer sides ot theguides, whereby the latches can swing to and from the guidesrwith theirfree ends projecting upwardly. The latches are each provided with a pairof flanges or wings 26 overlapping the respective guide 4- and providinga seat for the carrier 6, said flanges-projecting inwardly from theguide, as seen in Figs. 3 and 4:. Outstanding pins carried by the guidesl project loosely t rough the latches 24, and springs 28 upon said pinspress the latches toward the guides. The edges of the flanges 26 areinclined, whereby as the carrier 6 is raised, it moves past the latchesand presses thelatches outwardly, and when the carrier is moved abovethe flanges 26, the latches are snapped in wardly under the influence ofthe springs 28 to engage under the carrier, and thereby support it inraised position. The bars 7 are movable between the flanges 26 and donot engage therewith, so that said bars can be lowered while the carrieris held in raised position, thus permitting the plates 17 and :31. toswing downwardly within the carrier 6.

In order to simultaneously release all of the latches from the carrier6, longitudinal rock shatts 29 are disposed at opposite sides of theframe, and are journaled in bearings 30 secured to the standards orposts 2, and said shafts are provided with cranks 31 engaging behind theupper terminals or the latches 24-. The cranks 31 are normally swungagainst the guides 4: by the latches, and when the shafts 29 are swungin the proper direction, the c anlrs 31 are mover away from the guideswhereby to retract the latches from the carrier, to enable the can rierto be lowered. Each shaft 29 is pro video at one end of the trains withan arm 32, and said arms are connected by liults with an oscillatorydisk or lever mounted loosely upon one end'ol the shaiit 1'2. cable orflexible element connected with the lever 3-1: is slidable through aguide carried by the frame, and said cable can be extended. to a si"ible point to be pulled whereby to swing the lever 3st for pulling thelinks and swinging the arms to ward one another, thereby moving thecranks 31 outwardly to retract the latches.

In operation, when the dirt holding means is in lowered position, thebars '7 rest upon the ground. or underlying surface, and the carrier 6.rests upon the end portions of said. bars, the inner wings oil theplates 2i also if 11g upon the plates 17 and the plates 17 Jig upon thebars 7, whereby the plates are in a substantially horizontal planeiinniediately adjacent to the ground or undcrlying surface. The dirt orother material then shoveled or dumped onto the plates,

Fill

which can be done conveniently, and when the plates are tilled, the dirtholding means is elevated. This is accomplished by pulling cable l t bythe use of draltanimals,a windlass, or other suitable means, whereby tounwind the cable 141: from the drum 13 and to wind the cables 9 upon thedrums 11. This will raise the bars 7 which will elevate the :arrier t3and its plates also. i l hen the carrier moves past the latches 52mlthey snap under the carrier, and the cable 1 L is then .-=lacl ened,which permits the bars 7 to gravitate. tjlaid bars 7 can gravitate untilthe stops 'l'i' at the upper ends of the rods 8 contact with the carrier6. Due to the tact that the bars 7 are lowered away from the carrier,this enables the plates 17 to swing lown'n'arrlly under the weight ofthe 1na lerial, the inner wings of the plates 21 also swingingllownwardly between the plates 17 as seen in Fig. l. The downwardmovement oil the inner wings of the plates 21 is limited by the plates1'7 and the downward increment of the plates 17 limited by the bars Theplates and it? in being swung ilewnwanlly will provide a hopper, thelates 2'1 titling between the plates 17 and the latter separating toprovide a discharge opening, and due to the inclination of the plates,the material will gravitate down through the opening provided into thewagon or other receptacle which is moved nude;- the. carrii-u atter itwas raised. When the plate. are swung downwardly, the plates ll will litsnugly between the plates 17, and there tore prevent leakage past theside edges oi the plates 21, thereby confining the dis chargeot-material to the opening defined by the free edges ol the plates. llhematerial is thus readily raised and dumped into the wagon or receptacle.Then, after the wag-en or receptacle is moved out from undiathe :lrame,the apparatus is restored. This is accomplished by again pulling thecable let to in" e the bars 7, which will swing the inner wings of theplates :21 upwardly with the plates 1.? within the carrier. The carrieris raised slightly from the latches, and the ca le 35 is then pulledwhereby to re ract the latches, after which the cable lat is lackened,allowing the carrier 6 and corresponding parts ol' the dirt holdingmeans to gravitate to lowered position for again iweiving the material.

in view of the .lorcgoing, taken in connection with the drawin theadvantages and attributes oi" the n'csent invention will no doubt beapparent to those familiar with the art, without further descriptionbeing necessary.
